Yes, you can switch from Medicare Advantage to Traditional Medicare, but only during specific windows

You are not locked into a Medicare Advantage plan permanently. You can return to Traditional Medicare (Original Medicare), but the timing matters. Most people can switch during the Annual Enrollment Period (AEP), which runs October 15 to December 7 each year. Some people may have access to for a Special Enrollment Period (SEP) outside these dates if they have had a may have access to life event — moving out of the plan's service area, losing employer coverage, or experiencing certain other changes.

The key difference: during AEP, you can switch without proving a reason. During a SEP, you must document why you are switching, and the window is usually just 60 days. If you miss both, you are stuck with your current plan until the next AEP arrives.

Key Takeaways

  • The Annual Enrollment Period (October 15 to December 7) is when any Medicare Advantage member can switch to Traditional Medicare without a reason.
  • If you move, lose employer coverage, or experience other may have access to events, you may have a Special Enrollment Period lasting 60 days to switch outside of AEP.
  • When you switch to Traditional Medicare, you will need to enroll in a Medigap or Medicare Part D plan separately, because Original Medicare does not cover prescription drugs or many out-of-pocket costs.
  • Your new Traditional Medicare coverage starts on January 1 if you switch during AEP, so notify your current plan by December 7 at the latest.
  • If you are switching because your doctor left your plan's network, that may may have access to as a SEP, allowing you to switch before October.

How to switch during the Annual Enrollment Period

During AEP (October 15 to December 7), you can switch to Traditional Medicare by contacting Medicare directly. Call 1-800-MEDICARE, visit Medicare.gov, or speak to a Social Security office in person. You do not need to contact your current Medicare Advantage plan first — Medicare will handle the disenrollment for you.

When you call or go online, tell Medicare you want to switch to Original Medicare. They will confirm your identity, ask which plan you are leaving, and process the change. Your new coverage begins January 1 of the following year. Your Medicare Advantage plan ends on December 31.

Do not wait until December 7. If you call on December 6 and the line is busy, you may miss the important date. Call by early December to leave time for processing and to confirm the change went through.

may have access to for a Special Enrollment Period outside of October to December

A Special Enrollment Period (SEP) lets you switch outside of AEP if you have a may have access to event. Common reasons include moving out of your plan's service area, losing employer-sponsored coverage, becoming may be able to access for Medicaid, or having a family member die. Some plans also grant a SEP if your doctor or hospital leaves the network mid-year.

When you have a SEP, you usually have 60 days from the date of the may have access to event to switch. The clock starts the day the event happens, not the day you find out about it. If your doctor leaves the network on June 15, your 60-day window opens June 15 and closes August 14. After that, you cannot switch until the next AEP.

To use a SEP, call Medicare at 1-800-MEDICARE and explain the may have access to event. Have documentation ready: a lease or utility bill if you moved, a letter from your employer if you lost coverage, or a notice from your plan if your doctor left the network. Medicare will verify the event and process your switch if it qualifies.

What you need to do after switching to Traditional Medicare

Switching to Traditional Medicare is only the first step. Original Medicare covers hospital (Part A) and medical (Part B) services, but it leaves you responsible for deductibles, coinsurance, and copayments. Most people buy a Medigap policy to cover these gaps, or they enroll in a Medicare Part D plan for prescription drug coverage.

You have a limited window to enroll in Medigap without penalty. If you are switching from Medicare Advantage to Traditional Medicare, you have 63 days from the date your Advantage plan ends to enroll in a Medigap policy. After that window closes, insurers can charge you a higher premium or deny you coverage altogether, depending on your state.

For Part D (prescription drugs), you can enroll during AEP or during your SEP. If you do not enroll when you are first may be able to access, you will pay a late enrollment penalty for as long as you have Medicare. Enroll in Part D at the same time you switch to Traditional Medicare to avoid this penalty.

Common reasons people switch and what to watch for

The most common reason to switch is that a preferred doctor or hospital is no longer in the plan's network. Medicare Advantage plans can change their networks each year, and sometimes a specialist you rely on drops out mid-year. If this happens to you, contact your plan first to confirm the provider is truly out of network. If they are, ask the plan whether you may have access to for a SEP. Some plans will grant one; others will not.

Another frequent reason is cost. Medicare Advantage plans have low or zero premiums, but they often have higher deductibles and copayments than Traditional Medicare plus Medigap. If you are using a lot of medical services, the out-of-pocket costs can add up. Switching to Traditional Medicare with a Medigap plan may cost less overall, but you need to compare the premiums and out-of-pocket limits side by side.

A third reason is moving. If you relocate to a state or county where your current plan does not operate, you automatically may have access to for a SEP. Your plan will notify you if this happens, but do not assume — call your plan and ask whether your new address is in their service area.

Timing and what happens to your current coverage

If you switch during AEP, your new Traditional Medicare coverage starts January 1 and your Medicare Advantage plan ends December 31. There is no gap, but there is also no overlap. Make sure any prescriptions you need are filled before December 31, because your Advantage plan's pharmacy network will no longer work on January 1.

If you switch using a SEP, the timing depends on when you notify Medicare. Generally, your new coverage starts the first of the month following the month you request the change. So if you call on June 15, your new coverage might start July 1 or August 1. Ask Medicare for the exact start date when you request the switch.

Your current Medicare Advantage plan will send you a disenrollment notice confirming the date your coverage ends. Keep this notice for your records. If you do not receive it within two weeks of switching, call your plan to confirm the change was processed.

Frequently Asked Questions

Can I switch back to Medicare Advantage after switching to Traditional Medicare?

Yes, but only during AEP. If you switch to Traditional Medicare in January and then change your mind in March, you cannot switch back to Advantage until October 15. You are locked into Traditional Medicare for the rest of the year. Plan your switch carefully.

What if my doctor is no longer accepting Medicare?

If your doctor stops accepting Medicare altogether (not just your plan), switching plans will not help. Call your doctor's office to confirm whether they accept Medicare and which plans they participate in. If they do not accept Medicare at all, you will need to find a new provider regardless of which plan you choose.

Do I have to enroll in Medigap when I switch to Traditional Medicare?

No, but most people do. Without Medigap, you pay the full deductible and coinsurance amounts out of pocket. Some people choose Medicare Part D only (for drugs) and self-insure the medical gaps. This works only if you have savings to cover unexpected costs.

Will I have a gap in coverage if I switch during a SEP?

Usually not, but it depends on the exact dates. When you request a SEP switch, ask Medicare for your start date and your current plan's end date. In most cases, your new coverage begins before your old coverage ends, so there is no gap. Confirm this in writing.

Can I switch if I am on a Medicare Advantage plan through my employer?

Yes, but losing employer coverage is a may have access to event for a SEP, not a reason to switch during AEP. If your employer plan ends, you have 60 days to switch to Traditional Medicare. If you leave your job but your employer plan continues, you can still switch during AEP, but not outside of it.
